-----Original Message----- Subject: reverse proxy identification
When I browse to the IPs with firefox, I recieve several messages "No web
site is configured at this
address." for some IP. Does anybody here know if this message is specific to a given reverse
proxy/web server product ? That's an IIS message. For evidence of a reverse proxy - particularly one that's doing app firewalling - look for it to block stuff that's attack-like. For instance: Request: /sexpistols.asp?track=god%20save%20the%20queen Response: 200 Request: /sexpostols.asp?track=anarchy/../in/../the/../uk Response: 302, 404, or some other response that suggests the app never saw your request If you're using Nessus, recent versions will often report the presence of urlscan when a web app 'firewall' is in front of the actual web server.
